From a variety of perspectives, the essays presented here explore the profound interdependence of natural philosophy and rational religion in the `long seventeenth century' that begins with the burning of Bruno in 1600 and ends with the Enlightenment in the early Eighteenth century. From the writings of Grotius on natural law and natural religion, and the speculative, libertin novels of Cyrano de Bergerac, to the better-known works of Descartes, Malebranche, Cudworth, Leibniz, Boyle, Spinoza, Newton, and Locke, an increasing emphasis was placed on the rational relationship between religious doctrine, natural law, and a personal divine providence. While evidence for this intrinsic relationship was to be located in different places - in the ideas already present in the mind, in the observations and experiments of the natural philosophers, and even in the history, present experience, and prophesied future of mankind - the result enabled and shaped the broader intellectual and scientific discourses of the Enlightenment.

In this groundbreaking collection of essays the history of philosophy appears in a fresh light, not as reason's progressive discovery of its universal conditions, but as a series of unreconciled disputes over the proper way to conduct oneself as a philosopher. By shifting focus from the philosopher as proxy for the universal subject of reason to the philosopher as a special persona arising from rival forms of self-cultivation, philosophy is approached in terms of the social office and intellectual deportment of the philosopher, as a personage with a definite moral physiognomy and institutional setting. In so doing, this collection of essays by leading figures in the fields of both philosophy and the history of ideas provides access to key early modern disputes over what it meant to be a philosopher, and to the institutional and larger political and religious contexts in which such disputes took place.

A team of leading scholars survey the development of philosophy in the period of extraordinary intellectual change from the mid-16th century to the early 18th century. They cover metaphysics and natural philosophy; the mind, the passions, and aesthetics; epistemology, logic, mathematics, and language; ethics and political philosophy; and religion.

Scholars have long argued over whether the 1648 Peace of Westphalia, which ended more than a century of religious conflict arising from the Protestant Reformations, inaugurated the modern sovereign-state system. But they largely ignore a more fundamental question: why did the emergence of new forms of religious heterodoxy during the Reformations spark such violent upheaval and nearly topple the old political order? In this book, Daniel Nexon demonstrates that the answer lies in understanding how the mobilization of transnational religious movements intersects with--and can destabilize--imperial forms of rule. Taking a fresh look at the pivotal events of the sixteenth and seventeenth centuries--including the Schmalkaldic War, the Dutch Revolt, and the Thirty Years' War--Nexon argues that early modern "composite" political communities had more in common with empires than with modern states, and introduces a theory of imperial dynamics that explains how religious movements altered Europe's balance of power. He shows how the Reformations gave rise to crosscutting religious networks that undermined the ability of early modern European rulers to divide and contain local resistance to their authority. In doing so, the Reformations produced a series of crises in the European order and crippled the Habsburg bid for hegemony. Nexon's account of these processes provides a theoretical and analytic framework that not only challenges the way international relations scholars think about state formation and international change, but enables us to better understand global politics today.

The Protestant and Catholic Reformations thrust the nature of conversion into the center of debate and politicking over religion as authorities and subjects imbued religious confession with novel meanings during the early modern era. The volume offers insights into the historicity of the very concept of “conversion.” One widely accepted modern notion of the phenomenon simply expresses denominational change. Yet this concept had no bearing at the outset of the Reformation. Instead, a variety of processes, such as the consolidation of territories along confessional lines, attempts to ensure civic concord, and diplomatic quarrels helped to usher in new ideas about the nature of religious boundaries and, therefore, conversion. However conceptualized, religious change— conversion—had deep social and political implications for early modern German states and societies.

What did it mean to believe in alchemy in early modern England? In this book, Bruce Janacek considers alchemical beliefs in the context of the writings of Thomas Tymme, Robert Fludd, Francis Bacon, Sir Kenelm Digby, and Elias Ashmole. Rather than examine alchemy from a scientific or medical perspective, Janacek presents it as integrated into the broader political, philosophical, and religious upheavals of the first half of the seventeenth century, arguing that the interest of these elite figures in alchemy was part of an understanding that supported their national—and in some cases royalist—loyalty and theological orthodoxy. Janacek investigates how and why individuals who supported or were actually placed at the traditional center of power in England’s church and state believed in the relevance of alchemy at a time when their society, their government, their careers, and, in some cases, their very lives were at stake.
